Patented March 17, 1908;

Application filed June 22, Serial No. 380,205.

To all whom it may concern:

Be it known that I, CHARLES W. CooK, a citizen of'the United States, and residing at Holyoke, in they county of Hampden and State of Massachusetts, have invented certain new and 'useful Improvements in Combination Envelope and Letter-Sheets, of which the following is a specification, such as will enable thoseskilled in the art to which it appertains to-make and use the same.

his invention relates to stationery and particularly to what are known as combination envelope-and letter sheets, and the object thereof is to provide an improved device of this class comprising a blank composed of main and supplemental sheets, the main sheet serving as the envelop and the su plemental sheet as a letter sheet, and t e main sheet be' larger than the supplemental sheet, and l'lie said sheets being so permmed that when the letter or communication is written on the supplemental sheet, the latter may be folded over the main sheet and said sheets folded transversely so as to form an envelop of the usual form, in which osition of the parts three of the edges may e sealed together, and three edge portions torn off along the perforated lines in the operation of opening the envelop which operation will separate the letter sheet from the envelop. I

' The invention is fully disclosed in the following specification,. of which the accomforms a part, in which the separate parts my improvement are designated by suitable reference characters in each of the views, and in which 2-- Figure lis a plan view of my improved combination and letter sheet; Fig. 2 a view showing the supplemental or letter sheet folded over the mainor envelop sheet; Fig. 3 a view similar to Figs. 1 and 2, but showing the folded sheets shown in Fig. 2 folded on the line a:x of said figure; Fig. 4 a section on the line 4-4 of Fig. 2; Fig. 5 a section on the line 55 of Fi 3; and, Fig. 6 a section on the line 6-6 of ig.- 3.

In the practice of my invention, I provide a combination envelop and letter sheet composed of the blank a shown in Fig. '1, said lank being cut from any suitablepaper, and

the blank .a comprises a main or envelop sheet a and a supplemental or letter sheet a. The sup lemental or letter sheet a is shorter an narrower than the main or envelop sheet a and is adaptedto be folded alon the dotted line a over the main or enve op sheet as shown in Fig. 2. The main or envelop sheet is provided adjacent tothe dotted line a and parallel therewith with a row of perforations b, and the sup lemental or letter sheet a. is provided paralle with the dotted line a. and at a distance therefrom equal to the distance therefrom of the row of perforations b with a row of perforations b and when the supplemental sheet a is folded over the main sheet (1 the row of perforations will register with the row of per forations b. is also provided with two end rows of perforations b and the edge portion thereof,

opposite the folding line a, is provided with a row of perforations b, and that portion of the main or envelop sheet Within the rows of perforations b and b is of the same dimen- 'sions as the foldin supplemental sheet a The rows of perforations b and 13 form on the main or envelop sheet end margin stri s c and a side margin'stri c and one of t e end margin strips 0 and alf of the adjacent side margin strip 0 are gummed on the inner side as shown at d, and the back of the fold-. ing supplemental sheet a between the row of perforations b and the folding line a. is gummed adjacent to the gummed margin d of the main sheet a as shown at d in Fig. 2. In practice, the letter or other communication may be written on one or both sides of the folding or sup lemental sheet a after which said sheet is olded on the dotted line a. over the body part of the main or envelo sheet a. as shown in Fig. 2. The folded sheets a and a as shown in Fig. 2 are then The main or envelop sheet a folded on the line xa: or centrally thereof into the form shown irnFig. 3, and the en-..

ve'lop is then ready to be sealed and the three marginal edges e, e and c are sealed together, and all that is necessary to open the envelop is to tear off the marginaledges e, e and c and this operation separates the .supplemental or letter sheet a from the main or envelo sheet 0 In this way, I provide a combination envelop and letter sheet which together involves only an amount of material equal to that usually employed in the ordinary letter sheet, and at the same time I provide means where the packing, shipping, sale and use of stationery for letter or similar urposes are facilitated, as an desired numher of sheets or thickness slmilar to that shown in Fig. 1 may be packed in a box or boxes, and my improvement, as will be -'understood, avoids the use vof separate envelops and the necessity of placing ackages gf envelops and writing paper in t e same ox. v

This device may also be used by insurance companies and other com anies for sending out statements of various liinds and classes, the statements being printed on the supplemental or folding sheet a and when the envelop is open and the supplemental or folding sheet separated from the envelop part thereof, the said statementmay be conveniently carriedin the pocket or in a pocketbook designed for this purpose.

Ha fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

- 1 members; parallel lines of perforations at the I. A combination envelop and letter sheet comprising a main body member and a supplemental folding member integrally connected with'one side edge thereof, a folding line at the point of connection betweensaid opposite sides of said folding line, and lines o perforations extending around the main member at both ends and at the side edge thereofv opposite the folding member and forming in the main member a body portion if the same dimensions as the folding memer. p 2. A combinationenvelop and letter sheet,

plemental folding member integrally connected with one side edge thereof, a folding line at the point of connection between said members, parallel'lines of perforations at the 'opposite sides of said folding line, and lines of perforations extending around the main member at both ends and at the side edge thereof opposite the folding member and forming in the main member a bod portion of the same dimensions as the foldmg'member, one of the end strips of the body member formed by the adjacent end row of perforations being ummed on its inner side and the adjacent slde strip formed by the row of member perforations op osite the fol being gummed for half its 1635f, and the correspondi folding mem length.

3. A combination envelop and letter sheet comprising a main body member and a supplemental folding member integrally connected 'With one side edge thereof and separated therefrom by a folding line, paral el lines of perforations at the opposite sides of part or strip of the back of the er being gummed for half its said folding line, and lines of perforations eX- l tendin around the main member at both ends t ereof and at the side edge thereof opposite the folding memberthe folding member being smaller than the main body member.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing Witnesses this 2O dayv of June 1907. comprising a main body member and a sup- CHARLES W. COOK.
